NAME

XkbGetKeyExplicitComponents − Obtain the explicit components (the explicit array) for a subset of the keys in a keyboard description

SYNOPSIS

Status XkbGetKeyExplicitComponents

(Display *dpy, unsigned int first,

unsigned int num, XkbDescPtr xkb);

ARGUMENTS

− dpy

connection to server

− first

keycode of first key to fetch

	− num		number of keys for which to get explicit info
	− xkb		Xkb description in which to put results

DESCRIPTION

Whenever a client remaps the keyboard using core protocol requests, Xkb examines the map to determine likely default values for the components that cannot be specified using the core protocol (see Core Keyboard Mapping to Xkb Keyboard Mapping Transformation for more information on how Xkb chooses the default values).

DO THE FOUR PAGES OF "CORE KEYBOARD MAPPING TO XKB KEYBOARD MAPPING TRANSFORMATION" NEED TO BE ADDED HERE?

This automatic remapping might replace definitions explicitly requested by an application, so the Xkb keyboard description defines an explicit components mask for each key. Any aspects of the automatic remapping listed in the explicit components mask for a key are not changed by the automatic keyboard mapping.

The explicit components masks are held in the explicit field of the server map, which is an array indexed by keycode. Each entry in this array is a mask that is a bitwise inclusive OR of the values shown in Table 1.

XkbGetKeyExplicitComponents sends a request to the server to obtain the explicit components for num keys on the keyboard starting with key first. It waits for a reply and returns the explicit components in the server->explicit array of xkb. If successful, XkbGetKeyExplicitComponents returns Success. The xkb parameter must be a pointer to a valid Xkb keyboard description.

If the server map in the xkb parameter has not been allocated, XkbGetKeyExplicitComponents allocates and initializes it before obtaining the actions.

If the server does not have a compatible version of Xkb, or the Xkb extension has not been properly initialized, XkbGetKeyExplicitComponents returns BadMatch. If num is less than 1 or greater than XkbMaxKeyCount, XkbGetKeyExplicitComponents returns BadValue. If any allocation errors occur, XkbGetKeyExplicitComponents returns BadAlloc.

DIAGNOSTICS

	BadAlloc		Unable to allocate storage
	BadMatch		A compatible version of Xkb was not available in the server or an argument has correct type and range, but is otherwise invalid
	BadValue		An argument is out of range

Free Software

Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.
